Relative efficiency of rice-fish-duck production under integrated and conventional farming systems

Microbial preparations improve mineral nutrition of plants, protect against phytopathogens, and increase their resistance to stress factors. The aim of our research is to study the effect of microbial preparations on the biological activity of rhizosphere and the productivity of oil flax under no-till in the Crimean Steppe. Microbiological analysis of the rhizosphere of oil flax showed that there is a tendency to increase the number of microorganisms of various ecological and trophic groups both under the conditions of the conventional farming system (CFS) and no-till when seeds are inoculated with a complex of microbial preparations (CMP). Under CFS, the number of microorganisms using mineral forms of nitrogen as nutrition increased by 28 %; pedotrophs – by 37 %; ammonifiers and oligotrophs increased under both farming systems. The total number of nitrogen fixers increased by 29 % under CFS as a result of biological preparations use, while under no-till there was only a trend towards increasing the amount of azotobacter. The number of actinomycetes increased under the influence of CMP by 50% under direct sowing; micromycetes decreased under both farming systems. The number of cellulose-degrading microorganisms increased by 18 and 27 % under no- till and CFS, respectively. The yield of oilseed flax under no-till was 0.11 t/ha (12.9 %) higher than under conventional farming system. On average, over three years (2017-2019), an increase in yield amounted to 0.12 t/ha (19%) due to the use of microbial preparations.

A substantial proportion of beef production in Colombia originates in its extensiveEastern Plains. However, in this scenario and in a global context, demand for cattleproduction increasingly requests that it satisfies social and environmental expectationsin addition to being economically efficient. A dataset containing five-year long recordsof cow-calf production systems collected at Carimagua Research Centre located in theMeta Department was retrospectively interrogated to understand the liveweight (LW)-derived flux matrix dynamics of methane (CH4) emissions. Estimated total CH4 (kg)emissions during the gestation period, were similar between conventional weaned (CW;37.86 ± 0.506 kg) and early weaned (EW; 37.47 ± 0.476 kg) cows. However, averagedover two lactations, total CH4 emissions were larger (p < 0.0001) in CW cows (38.67± 0.456 kg) than in their EW (14.40 ± 0.435 kg) counterparts. Total gas emissionsfrom birth to comparable commercial yearlings age were higher (p < 0.0001) for CW(43.11 ± 0.498 kg) calves than for EW (40.27 ± 0.472 kg) calves. It was concluded thatmid and long-term pastoral datasets and new concerns are well suited to understanddifferent contexts and adaptations to the contemporary weather conditions. Nevertheless,conventional farming systems will be less environmentally vulnerable if EWmanagement practices involve the strategic and temporal use of improved pastures. Theroles of veterinary medicine and animal sciences are briefly discussed in the context ofunprecedented climate variability to provide a guide to the uncertain future.
